Programmable climate controller for a vehicle

1. A programmable controller comprising: electrical circuitry associated with a plurality of vehicle functions; a memory for storing operating data associated with functions in a defined plurality of vehicles; a first connector half that is electrically connected with the controller and has a plurality of pins configured to mate with mating pins in a second connector half associated with a selected vehicle among the defined plurality of vehicles; the first connector half mates with the second connector half and connects the electrical circuitry in the controller with the selected vehicle's electrical circuitry; a first electrical circuit among the controller's electrical circuitry detects a battery connection and ignition activation in the selected vehicle and retrieves the selected vehicle's vehicle identification number; and, a second electrical circuit among the controller's electrical circuitry responds to the first electrical circuit detecting the battery connection and ignition activation in the selected vehicle, retrieves data from the memory according to the selected vehicle's vehicle identification number, and programs the controller for controlling selected functions in the selected vehicle.

2. The programmable controller of claim 1 , wherein the memory stores operating data associated with functions in at least three vehicle groups among the plurality of vehicles.

3. The programmable controller of claim 1 , wherein the programmable controller is contained within a housing that contains the plurality of pins configured to mate with mating pins in the second connector half associated the selected vehicle.
